A filling device, in accordancewiththis invention, comprises .a .tubularbody portion referred to generally by ithe reference character'land consisting ofa'ca'stingriiormed of an intermediatepart 2,.an Aentere-,11d part 3 and an inner end-part 4,. andthe latter has its inner terminus formed with,` an'interiorly threaded annular collar-*5 ofthe same louter diameter as the louter diameter ott-he part l andhafvingwits inner diameter greater than the innerfdiameter ofthe.p`art4. The inner diameter ot the parts 2, Scand 14:; is f the same with respect to eachother;V The youterend part 3 is formed of two spaced segmentahsections-657, thereby providing'the outer end of the tubular body/.portionl :with a-lengthwise extending diametrically jdisposed slot or passage 8. The outer terminusot each of they sections 6, 7 `is formed with.` an inwardly extending segmentaleshaped flange 9. The

anges- 9 .are oppositely disposed and each has its free ledge ,viush lwiththe lengthwise edges kof 'itsrespective section.

Theouter end part i3 isfformedwitha pair -ot opposed openings l0 and each of lsaid openings-1s formedin a-seetiolr or .7 in proximity to .theginner lfaceot a'liangey). The openings 10 are arranged adjacent the axis `of the tubularbody portiongl'andpositioned against theper-iphery ottheouter end part Sis a pair of oppositely disposedwashery elements 11 Vhaving their -innerfaces conforming yto the `arc offthe'periphery 'of the outer endpart 13. :The openings formed-by the washer elements register with the openings yl0.v ,Extending through the washer) elements ll-and,y openings l() is a `pivot Vbolt 12 provided with. a; head lWhich iabu'ts against one of the washerfelements 1l and further provided with alclamping nut 14, which lila? The inner end part of the tubular body portion 1 is of greater outer diameter thanV the outer diameter of the part 2 or part 3. whereby said ,part 4 is of greater thickness than the other parts of the tubular body portion 1. The thickened part 4 reinforces the inner end of the tubular body portion 1.and said part v4 is formed with a lateral opening 15 providing aninlet for inserting the lubricant or grease into the body portion 1 and which is to be expelled from said body portion into the lubricant receiving cup, not shown. Tliel diameter of the opening 1 5 is slightly less than the length of the part 4. f y

Arranged within the tubular body portion 1 and of less length than the length of the latter, is a closure element 16 for the opening 15 andwhich is of a length slightly less than the combined length of the parts 2 and 4. The element 16 is in the form of a. sleeve or bushing and is of an outerv diameter to snugly engage the innerface of. the tubularbody portion 1. The element 16 is shiftable lengthwise with respect to the body Yportion f 1 Vwhen moved to and from closure position other projecting end threaded, as at- 21,

with respect to the opening-15. The element 16 is manually shifted to and. from closure position,through the Amedium of a rod 17, which extends diametrically of the element 16 and body portion 1 and further extends through a pair of opposed openings 18 formed in the element 16. The rod 17 operates in a'pair of opposed, lengthwise extending slots 19 formed in the parts 2 and 4 of the body portion 1.

Tlie element 17 projects from the tubular body portion 1 and has one of its projectiiig'ends in the form of ahead 20 and its for the reception of a cap nut 22. The head 20 iii connection with the nut 22 detachably connects the rod 17 tothe tubular body portion 1.l and further prevents the rod 17 from shifting diametrically with respectto said body portion 1.v u e Operating within the tubular body portion 1 andalso in the closure element 161s a. lubricant expelling'plunger consisting of an intermediate portion 23, an inner end portion 24 and an outer end portion 25.

The portions 23 and 25 are tubular in con-v tour and the portion 25 is of greater outer diameter than' the portion 23, therebyprovidinga shoulder 26. The inner end portion 24 of the plunger constitutes'a head therefor yand it consists ofI aucircular'disk providedoii its upper or inner facewith aY periplierally threaded collar 27 positioned Vreceding movement of the expelling` plunger to prevent the withdrawal of the lubricant or grease after it has been supplied to the lubricant receiving cup. v

rllie intermediate portion 23 is tubular,.- opeii at its inner end and formed with an integralclosure 30 at its outer end. .The inner end of the intermediate portion 23,;is reduced, as at 31, and interiorly tlireadet'i. The reducedinner end 31 provides an annular shoulder 32 on the inner face of the intermediate portion 23 and .against said shoulder abuts the collar 27. on the collar 27 andreduced portion '31 provide means for detachably connecting the inner end portion 24 or plunger head to the intermediate portion 23, and thelatter is formed with a pair of lengthwise extending opposed slots 33 through which the rod 17V extends. align with the slots 19 of the tubular body portion 1. f.

The outer end portion 25 of the expelling plunger is formed substantially solid and The slots 33 are adapted to The threads provided with fa diametrically extending` groove 34 of the same width as the width of the slots or passages 8, and said groove is adapt-ed to register with thesaid slots or passages 8. rlChe groove is of less depth than the height of the portion 25 and open at the top of the latter. ofthe groove 34, and intersecting the verticalmedian ofthe portion 2 5 is a cylindrical pin 35, which is anchored in' the portion 25 of the expelling plunger.' Mounted in the bottom of the groove 34 tofoiie side Extending transversely of tliepin 35 and extending into the groove Yotally mounted on the bolt 12 and rides between the pin 35 and bearing 36,. Formed integral with the Cain 36 is a handle ineinber 37. line position shown in Figure 2, the expelling plunger is forced to the position shown in Figure 2, .and when the 021111.36 is kshifted tothedotted line position Figure 2,

the expelling plunger is withdrawn as indillO When the cani 36 is shifted to full l cup.

to the lubricant z receiving cup, and said,

spud 39 directs the expelled lubricant to such rlhe inner vdiametervat the -outer or upper endof the spud 39 is the same as the outer diameter of the expelling plunger and by this arrangementthe spud projects inwardly from the inner end part t of the tubular body portion 1 and provides a seat 40 for the closure element lit-when the latter is shifted to close the opening 15. rlhe top edge of the element 16 coacts with the shoulder 26 of the expelling plunger for limiting '"or arrestingthe expelling action thereof.

With yrespect to Figure'1'O,-a modified form of spud is indicated at i1 and which is closed atits inner end, as at 4Q, and formedwith a. pair of l'lateral openings@ in proximity to the closed endlf, to provide `for the lateral discharge of the lubricant expelled from the filling device. V'The spud l1 is adapted to beV connected to the collar-5 and'provides a seat for the' closure element 16.

It will be assumed that the expelling plunger is in zdot-ted line position as shown in Figure Qand when the'plunger `is shiftedto i such position, the element 16 is carried therewith. lhen-the parts are in such position "the lubricant-is inserted through the opening 15,- after which `the element 16 isshifted through the medium of the rod 17 to the position shown in Figure 2 to close'theinlet.' The expelling plunger' is then operated through the medium of the cam in a downward direction 'for the lpurpose of forcing the lubricant into the cup or at any other desirable point. As the rod 17 extends through the slots in the plunger the closure element 17 is not shifted by the plunger when the latter is shifted in either direction by its operating means.

it is thought the many advantages of a lubricant expelling device, in accordance with this` invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, vet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
